USB-C PD power for phone + EFB habits on the road. We only list banks with published capacities under the common 100 Wh carry-on threshold. Always read the Wh label on your unit, keep spare banks in carry-on (not checked), and follow your carrier’s quantity / onboard-use rules — we do not invent airline policy.

Battery reminder (public FAA context): Spare lithium power banks generally must travel in carry-on, typically ≤100 Wh without airline approval. Confirm the printed Wh on your bank and your carrier’s current page before you fly — rules and quantity limits differ.

EFB iPads and phones die on long days when seat USB is weak or missing. A mid-size PD bank under 100 Wh covers phone + tablet top-ups without playing chicken with battery rules. Pair with a GaN wall charger so the bank itself recharges quickly in the hotel.

Anker Nano II 65W GaN charger
Hotel kit: Anker 735 Nano II 65W + USB-C cable
GaN wall charger · 240W-class USB-C cable
Room recharge
  • Charger: Anker 735 Charger (Nano II 65W) — compact GaN multi-port wall brick
  • Cable: Anker USB-C to USB-C rated up to 240W (e.g. 543 / Prime cable lines) — buy length you actually use (3–6 ft)
  • Kit price range: often ~$40–$70 combined depending on sales — check live
  • Role: Recharge the power bank + phone + iPad from one hotel outlet
  • GaN size fits a toiletry kit better than old 65W laptop bricks
  • A known-good high-watt cable prevents “why is this only 7W?” frustration
  • Complements any of the banks above
  • Hotel outlets and desk reach still vary — a 6 ft cable helps
  • International trips may still need a plug adapter (voltage is usually fine; pins aren’t)

Choose this wall kit so your bank isn’t a one-way battery. The bank saves the duty day; the GaN brick resets it overnight.
